Topic: This is a silly question - AB/BA

Some presets are AB and others BA. What does that mean? What is the difference?

I hope you don't mind asking,

I always assumed that it was indicating the orientation of the strings : Bass-Alto (Left-Right) or Alto-Bass.
But I don't know for sure.

Re: This is a silly question - AB/BA

No, presets don't change the model. AB/BA is about mics

Pianoteq 6 Pro (D4, K2, Blüthner, Model B, Grotrian, Ant.Petrof)
Studiologic SL88Grand, Steinberg UR22mkII

Swapped positions of mics 1 and 2.

Hard work and guts!

Re: This is a silly question - AB/BA

Still a bit puzzled, but I will look this up at Google.

Thank you,

AB means the lower notes come from the left (i.e. the left speaker) and the high notes from the right.
BA is the the other way round.

Here is how I understand it; perhaps this may shed some sound on what you are hearing:

When you are positioned at the right hand side of a grand piano, essentially standing at the curve where the Piano's wooden case gets thinner, you normally tend to hear the hammers towards your left, and the bass strings towards your right, because the bridge extends towards your right in that listening position.

This has confounded some listeners, because they believe the low notes should "sound" from the left, and the high notes should sound from the right.  The switch from AB to BA, effectively reverses the positioning of the microphones, such that you again hear the low notes come from the left and the higher notes coming from the right.


Personally, this regular "AB perspective" doesn't bother me at all; however, Modartt furnishes the choice of reversing the channels in case it happens to bother you.

Cheers,

Joe


P.S.  I have been gone from these forums for the past few months -- I broke the radius bone of my forearm as it goes into my left elbow.  I was in a cast for 6 weeks, and was unable to write my own name (being left handed), and there was little desire to go onto the internet and only click the mouse with my right hand, or type right-handed.  Hopefully, I should become more active on this site.

Hi Joe,

Besides enjoying Pianoteq these last few years,  it has been a great joy to read your comments and hear your renditions.  May God grace you with a sound recovery.

Re: This is a silly question - AB/BA

I second that. I have your Ravel Alborada Del Graciouso in my iTunes libary and I like it more then Thibaudet. Sorry if I missspelled any of those, lazy to look it up.

Say I'm working on a really great preset of the D4 with totally different tuning and set up and it sound soo lovely I'd love to hear I rendition of Alborada (the K1 never touched me as the D4 did)

Good description Joe.

I've been away for longer - quite busy with photography.

Sorry to hear about your accident.   Really hope that all is well and it won't have any lasting effects on you.

I'm also a leftie.

It's the other way round:

AB: Alto (higher) notes from the left, and Basso (lower) notes from the right. This is the audience position of listening to a piano, where the lower notes are more pronounced on the right and the higher notes on the left.

BA: Lower notes on the left and higher on the right. This is the piano players position of listening to a piano.

I checked this with HQ headphones. The difference between AB and BA is subtle, but distinct enough.

Have a nice day & happy playin'
